From Hellborg's website: 
 
[color=#000000]"Sound of Sweden" was the name of a brand Jonas created with some friends in order to produce the Jonas Hellborg bass in '82-'84.[/color] 
 
[color=#000000]He also created an amplifier line, in partnership FBT, based in Recanati, Italy. It was the first biamped bass amplifier, in which each cabinet had its own power amp - one for the 15" and one for the 2x12".[/color]

Yes i was wrong about it, it was the amp´s that came from Italy and the bass came from "Aria". 
The friends where infact the company Sound of Sweden as i recall it, and the same company where the importers for Aria in Sweden. 
My misstake sorry!
